PATENT OFFICE.

FREDERICK A. GERBER, OF NEW YORK, N. Y.

I REMOVABLE WINDOW-FRAME.

Specification of Letters Patent.

Patented Dec. 28, 1920.

Application filed November 29, 1916. Serial No. 184,073.

To all whom it may concern Be it known that I, FREDERICK A. GERBER, a citizen of the United States, residing at New York city, in the county of- New York and State of New York, have invented certain new and useful Improvements in Removable Window-Frames; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a window frame construction, and the primary object of the invention is to provide a window frame, the lower portion of which may be easily removed, for permitting of the removal of the window sash, when it is desired to clean, or repair the windows, or in cases where it is necessary to remove the window sash for moving large pieces of furniture into the room.

Another object of this invention is to provide a window frame construction as speci iied, the removable portion of which has spring controlled latches carried thereby which are seated in keepers or recesses formed in the window sill, and to form tongues upon the upper ends of the removable portions of the frame; which are seated in recesses formed in the lower ends of the stationary portions of the frame, whereby the removable portion of the frame will be held rigidly in its proper position, until it is desired to remove the same.

With the foregoing and other objects in view, this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters designate like and corresponding parts throughout the several views, and in which Figure 1 is a fragmentary view of a window constructed in accordance with this invcntion.

Fig. 2 is a vertical section through the Window.

Fig. 3 is a horizontal section through the window taken on the line 33 of Fig. 1.

Fig. 4 is a fragmentary enlarged horizontal section taken on the line 4-4 of Fig. 1.

Fig. 5 is a section on the line 5-5 of Fig. 4. v

Fig. 6 is a section on the line 6-6 of Fig. Y

Fig. 7 is a horizontal section of a modified form of the window frame.

Fig. 8 is a fragmentary edge View of one ofthe sashes, and

Fig. 9 is a fragmentary view partly in section and partly in side elevation of one of the sashes.

Referring more particularly to the drawings, 1 designates the window frame struc ture as an entirety, which includes the usual type of stone sill 2 and the wooden sill 3 together with the usual type of molding 4:. The lower portion of the frame proper, in which the lower sash 5 slides, and which includes the inner stop 6. parting strip 7 and portion 8 of the back, is removably connected to the upper corresponding portion 9 of the window frame through the medium of tongues 10. The stop 6, parting strip 7 and portion 8 of the lower portion of the frame proper are formed integral. The tongues 10 are formed upon metal sockets 11, which are mounted over the upper ends of the stop 6, parting strip 7 and the portion 8 of the frame, as clearly shown in Figs. 2 and 5 of the drawings. The tongues 10 are seated in reces es 12 formed'in the lower end of the upper rigid portion 9 of the parting strip, portion of the frame and stop. The lower ends of these members are reinforced by metallic caps 13 as clearly shown in Fig. 5.

The portion 8 of the frame is provided with a recess 14 formed in its lower end. the outer portion of which recess is closed by a plate 15. A locking latch 16 is slidably mounted within the recess and it is held in an extended position by means of a coil springl'Z. The plate 15 is provided with an indentation 18, in which is seated a rotary disk 19. The disk 19 is mounted upon a shaft 20 which extends through the plate 15 and has a pinion 21 mounted upon its inner end which meshes with rack teeth 22 formed upon the shank 23 of the locking latch 16 so that when the disk 19 is r0- tated, the locking latch 16 will be raised out of the recess 24, which is formed in the wooden sill 3, to permit the lower section of the window frame which is composed of the section 8, stop 6 and parting strip 7 to be removed from the stationary portion of the frame, to allow the sashes 5 and 5 to be removed from the window frame.

A keeper plate is mounted upon the upper surface of the wooden sill 3 and it extends about the recess 24. An upstanding projection 26 is formed upon the plate 25 and forms a stop for limiting the inward movement of the section 8, stop 6 and parting strip 7.

The sashes 5 and 5', are provided with recesses formed in their outer edges near their upper ends, in which recesses are seated plates 41. The plates 41 have hooks 42 formed thereon which extend outwardly into the recesses, and to which the looped ends 48 of the sash cord or weight cord 30 are connected, as clearly shown in Figs. 8 and 9 of the drawings.

lVhen it is desired to remove the upper and lower sashes 5 and 5, the disk 19 is rotated for moving the locking latch 16 upwardly out of the recess 24, after which the section 8, parting strip 7 and stop 6 are swung outwardly as indicated in dotted lines in Fig. 5, and removed from connection with the rigid portions of these members, after which the lower sash 5 is disconnected from the cord 30, which is connected to the usual weight 31, and it is lowered into the portion of the frame from which the removable members have been removed, whereby the sash may be easily and quickly removed. IV hen the sash cord 30 is disconnected from the usual weight 31, it is connected to a hook which is carried by the window frame, so as to prevent the sash cord from passing into the space 46, inwardly of the window frame and also for holding the looped end of the cord in convenient position to be reconnected to the hook 42 of the window sash. After the lower sash 5 has been removed, the upper sash 5' is lowered, and disconnected from its weight 31, and moved outwardly out of the frame. The outward movement of the upper sash 5 will be permitted, owing to the fact that the lower portion of the parting strip 7 has been removed from the window frame.

In Fig. 7 of the drawings, a modified form of the frame construction is shown, wherein the lower removable portion of the frame, comprising the stop 6, the portion 8 and the parting strip 7 are formed in one piece a in the original form. The parting strip 7 has a cut-away portion 9' formed in its inner surface, which receives a tongue 10 formed upon the stationary portion 11 of the window frame. In all other respects the modified form is identical with the preferred form as previously described.

In reducing the invention to practice, certain minor features of construction, combination and arrangement of parts may necessitate alterations to which the patentee is entitled, provided such alterations are comprehended within the scope of what is claimed.

What is claimed is A window structure including a frame and slidable sashes, upper and lower guide members for the sashes carried by the frame and each consisting of an inner stop, a parting strip and a back portion, the back portions of the upper guide members extending beyond the lower ends of the stops and parting strips of said upper guide members, the back portions of the lower guide members terminating short of the upper ends of the parting strips and stops of said lower guide members so as to receive the lower ends of the upper back portions and permit the ends of the lower parting strips and stops to project beyond the same and abut the lower ends of the upper parting strips and stop to form a firm and smooth connection between the upper and lower guide members and to permit the lower guide members to be swung laterallv and removed from the frame when it is desired to remove the sashes, tongue and 'oove connections between the upper and iovrer guide members, means detachably securing the lower guide members to the frame, said lower guide members having their lower ends disposed on an incline to permit swinging of the lower guide members in re lation to the frame, wear plates secured to the frame and engaged by the inclined ends of the lower guide members, and upstanding flanges formed on said plates for limiting the movement of the lower guide members in one direction.

In testimony whereof I aflix my signature in presence of two witnesses.

FREDERICK A. GERBER.
